Regardless of how Gustaffson does in this fight I still dont see him having a chance against Jones. Anderson Silva is the one fighter i'd like to see Jones fight.
Jones is too intelligent and confident. Everyone else that Silva faces buys into the mystique of his style (apart from Sonnen that one time) but Jones won't. He'll be smart enough to adapt and go to Silva's weakest areas and then outmuscle him.
Silva is likely to just come out and invent something like 'ear-lobe poking' or a 'flying chest-jab' on-the-fly and within the rules and then annoy the gameplan out of anyone. I'd far rather see him at GSP though. Either could be close fights.
